HOT-WATER HEATER FOR KITCHEN-RANGES.

SPECIFICATION forming part Of Letters Patent N0. 748,899, dated January 5, 1904. Application filed May 25, 1903. Serial No. 158,570- ll'o model.)

To all whom it may concern:

Be it known that I, PAUL WERNER, a citizen of the United States, residing at New-: ark, in the county of Essex and State of New Jersey, have invented'certain new'and use ful Improvements in Hot-Water Heaters for Kitchen-Ranges, an; and I do hereby declare the following to be a full, clear, and ex: act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same," reference being bad to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention has reference to improvements in hot-water generators which are applicable to kitchen-ranges and other similar "and small stoves; and the invention has for its principal object to provide a simple and practical hot-water heater which is to be used in connection with the fire-box or fire-chamber of akitchen-range or other small stove and is adapted more especially for use in flats and smaller buildings for the purpose of heat ing one or more rooms by means of hot-water circulating through a radiator or radiators directly connected with the boiler or water A still further object of this invention is a provide an arrangement of combined kitchenrange and hot-water heater, the latter being of such shape and construction that the arrangement of the heater above the fire will not interfere with the draft conditions of the range and will permit of the passage of the heat to the baking or roasting chamber or chambers of the range or stove in the same manner as is at present the case with the usual kitchen range or stove.

With these various objects of my present invention in view the same consists, primarily, in the novel construction of hot-water-heater for kitchen-ranges and other small stoves hereinafter set forth. Y

My present invention consists, furthemore, in the various novel arrangements and combinations of devices and parts, as well as in the details of the construction thereof, all of which will be fully described in the following specification and then finallyembodied in the clauses of the claim which are appended to and form a part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a kitchenrange and an end view of a radiator, illustrating one arrangement of pipe connections between the said radiator and the hot-water heater within the range or stove. Fig. 2 is a top view of the range or stove with its top plate and hole-covers removed, the said view illustrating in plan the arrangement of the heater or boiler within the fire-chamber of the range. Fig. 3 is a longitudinal vertical section of the range, the said section being taken on line 3 3 in said Fig. 2. Fig. 4 is a transverse vertical section of the heater in its de-' tached position from the range, the said section being taken on line 4 4: in said Fig. 2. Fig. 5 is a perspective view of the said heater.

' Similar characters of reference are employed in all of the said hereinabove-described Views to indicate corresponding'parts.

In the said drawings the reference character 1 indicates the complete range, which may he of any known construction, the same being provided with the usual grate 2 and fire-box or chamber 3, lined with fire-brick 4, as repcharacter 13 and is provided with the usual ornamental doors.

14 indicates the sides, and 15 the base, of the range.

Resting directly upon the upper marginal edges of the fire-brick 4 or upon other suitable supporting means is the hot-water heater or boiler 16. (Indicated in Figs. 2 to 5, inclusive.) The said heater, as will be seen more especially from an inspection of Figs. 3 and 4 and 5, consists, essentially, of a hollow casting, that in the present case being of a rectangular configuration, which conforms to the inner contour of the upper part of the firechamber 3, so as to be properly and snugly fitted in the said upper portion of the said fire-chamber, as clearly indicated in Figs. 2 and 3. It will be understood, however, that the configuration of the said casting may be varied, so. as to conform to the contour of the variously-shaped fire-chambers of other ranges or stoves. As will be seen from the several figures of the drawings, the said casting is made with suitably-disposed fire holes or openings 17, which correspond to the positions of the holes or openings in the top plate 11 of the range or stove, that the fire and heat from the fire-chamber ,4 can strike through the said holes or openings 17 and be brought directly beneath the bottom of a pot or kettle that may be placed in one ofthe holes 12 in said top plate 11, as will be clearly understood. The said casting may also be provided with suitable draft-holes 18 and 19, and to provide for sufficient water-space within the walls of the hollow casting one portion, as 20, is preferably made much higher than the remaining portion 21. From an inspection of Fig. 3 it will be seen that the higher portion 20 extends directly beneath the under surface of the top plate 11, or approximately so, while the portion 21, being much lower, provides a sufficient space for the passage of the fire and hot air coming from the various holes 17 and 18 and 19 into the flue or duct 6 directly above the chamber or chambers 5, so as not to interfere with the draft and heating properties of the range or stove for cooking or baking purposes.

Referring to Figs. 3 and 5, it will be seen that the metal walls which form the holes 17 preferably taper in an upward direction, as at 22, and are also made tapering, as at 23, to prevent the coal when poured into the openings from spreading over the upper surface of the reduced part 2101: the casting and at the same time acting as a kind of hopper for more readily conducting the coal into the fire-chamber. At the same time the raised portions 24, which surround the holes 17 and the draft-holes 19 in the manner represented more particularly in Fig. 5, form, with the under surface of the top plate 11, suitable pockets in which the heat is retained, and thereby help to more quickly heat the water which is contained in the said heatercasting 16. The said water-heater casting 16 is also provided in the upper surface at any suitable point withan outlet 25, with which is connected a pipe 26, leading to a radiator or radiators 27. A return-pipe leads from said radiator 27 to an opening 29 in the bottom of the heater-casing, as clearly indicated in dotted outline in Fig. 2 of the drawings, and connected with the said pipe 28 at any suitable point is a supply-pipe 30, having an inlet-valve 31 for admitting fresh water into the said heater-casing whenever necessary. The said pipes 26 and 28 are suitably connected with the casting 16 by means of water-tight and fireproof joints, and said pipes pass through suitably-disposed holes or openings in the side 14 or other suitable part of the range or stove, as will be clearly understood.

From the above description it will be evident that I have devised a simple and practical construction of hot-water heater for kitchen-ranges and other small stoves which can be economically manufactured and in which a rapid circulation of hot water is easily obtained without the use of additional fuel and at the same time utilizing the heat and hot gases which heretofore passed 01f through the chimney as waste.

Of course it will be obvious that changes may be made in the several arrangements and combinations of the devices and their parts, as well as in the details of the construction thereof, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the devices and their parts as described in the foregoing specification and as illustrated in the accom panying drawings, nor do I confine myself to the exact details of the construction of the said parts.

Having thus described myinvention, what I claim is 1. The combination, with a kitchen-range, of a hot-water heater arranged in said range, comprising, a hollow casting having two parts 20 and 21, one of which is higher than the other, said casting being provided with fireholes, and said higher part 20 being provided with heat-retaining pockets, substantially as and for the purposes set forth.
